True Bipolar Input, 12-Bit, 2-Channel, Simultaneous Sampling SAR ADC
The AD7366-5/AD7367-51 are dual, 12-/14-bit, low power, successive approximation analog-to-digital converters (ADCs) that feature throughput rates up to 500 kSPS. Each device contains two ADCs, which are both preceded by a 2-channel multiplexer, and a low noise, wide bandwidth, track-and-hold amplifier.
The AD7366-5/AD7367-5 are fabricated on the Analog Devices, Inc., industrial CMOS process (iCMOS®)2, which is a technology platform combining the advantages of low and high voltage CMOS. The process allows the parts to accept high voltage bipolar signals in addition to reducing power consumption and package size. The AD7366-5/AD7367-5 can accept true bipolar analog input signals in the ±10 V range, ±5 V range, and 0 V to +10 V range.
The devices have an on-chip 2.5 V reference that can be disabled to allow the use of an external reference. If a 3 V reference is applied to the DCAPA and DCAPB pins, the AD7366-5/AD7367-5 can accept a true bipolar ±12 V analog input. Minimum ±12 V VDD and VSS supplies are required for the ±12 V input range.
- True bipolar analog input signals can be accepted, as well as ±10 V, ±5 V, ±12 V (with external reference), and 0 V to +10 V unipolar signals.
- Two complete ADC functions allow simultaneous sampling and conversion of two channels.
- A 500 kSPS serial interface is SPI-/QSPI™-/MICROWIRE™-/ DSP-compatible.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
